Step-by-step explanation:

sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{1}[/tex]

hence x = sin30° = [tex]\frac{1}{2}[/tex]

and

cos30° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{y}{1}[/tex]

hence y = cos30° = [tex]\frac{\sqrt{3} }{2}[/tex]

Answer:

Last option: Keep the base the same and then subtract the exponents.

Step-by-step explanation:

There is a property called "Quotient of power property".

This property states that if you need to divide two powers with the same base, you must keep the same base and subtract the exponents:

[tex]\frac{a^m}{a^n}=a^{(m-n)}[/tex]

Then, you need to apply this property to the expression [tex]\frac{(3^{-6})}{(3^{-4})}[/tex] to simplify it.

Therefore, you get that the expression simplified is:

[tex]3^{(-6-(-4))}=3^{(-6+4)}=3^{-2}[/tex]

9/20 is coconut milk

The proportion of coconut milk in the fruit cocktail is 9/20, which is calculated by dividing the amount of coconut milk (45 ml) by the total volume of the cocktail (100 ml), then simplifying the fraction.

To find the proportion of coconut milk in the fruit cocktail, we first add up the total amount of all the liquids that go into the cocktail. According to the question, for every 25 ml of orange juice, there is also 30 ml of apple juice and 45 ml of coconut milk mixed together. Adding these amounts gives us a total mixture volume of 25 ml + 30 ml + 45 ml = 100 ml for the cocktail.

Next, we need to find out what fraction of this total mixture is coconut milk. Since there are 45 ml of coconut milk in the total 100 ml of the cocktail, the fraction is 45/100. This fraction can be simplified by dividing both numerator and denominator by the greatest common divisor, which is 5, giving us 9/20.

Therefore, the proportion of coconut milk in the fruit cocktail is 9/20.

Answer:

108.505

Step-by-step explanation:

Let's talk money for just a second. Which would you rather have 20 dollars or 20.32      20dollars and 32 cents?

Isn't 20.32 bigger than 20.

You should say yes.

If that is true, then 108.505 should be larger than 108.5 not by much, but still larger.

After comparing digits after the decimal point, 108.505 is greater than 108.5 because 505 is greater than 500.

When comparing two decimal numbers, you should compare them digit by digit, starting from the leftmost digit. In this case, both numbers start with 108, which is the same. However, when comparing the next set of digits after the decimal point, you have 505 for the first number and 5 (equivalent to 500) for the second number. Because 505 is greater than 500, the first number, 108.505, is greater than the second number, 108.5.

So first let’s put g(f(x)) together by putting f(x) for every x in g(x)

We get g(f(x))=3(3/4x+3)+4 which is the selling price equation

Then you plug in 20 to find the selling price for 20 muffins.

g(f(x))=3(3/4(20)+3)+4

g(f(x))=3(60/4+3)+4

g(f(x))=3(18)+4

g(f(x))=54+4

g(f(x))=58

So the selling price will be $58 for 20 muffins.

Final answer:

The zeros of the function h(x)=(-4x-3)(x-3) are x=3/4 and x=3, with the smaller solution being 3/4 and the larger solution being 3.

Explanation:

To solve for x, we need to find the zeros of the function h(x) = (-4x-3)(x-3). The zeros of a function occur where the function equals zero, so setting h(x) to zero gives us:

0 = (-4x - 3)(x - 3)

A function is zero when any of its factors are zero. We can, therefore, set each factor equal to zero and solve:

-4x - 3 = 0 => x = -3/(-4) => x = 3/4

x - 3 = 0 => x = 3

So the zeros of the function are x = 3/4 and x = 3. The smaller solution is x = 3/4, and the larger solution is x = 3.

Just multiply the numbers

Answer:

[tex]sin (-x) cos (-x) csc (-x) =cos(x)[/tex]

Step-by-step explanation:

We know by definition that the cosine is an even function, therefore

[tex]cos (-x) = cos (x)[/tex]

We also know that the sin is an odd function, therefore

[tex]sin (-x) = -sin (x)[/tex]

By definition:

[tex]cscx = \frac{1}{sinx}.[/tex]

Then:

[tex]csc(-x) = \frac{1}{sin(-x)}.[/tex]

[tex]csc(-x) = -\frac{1}{sin(x)}.[/tex]

Using these trigonometric properties we can simplify the expression

[tex]sin (-x) cos (-x) csc (-x)= -sin(x)cos(x)*(-\frac{1}{sin(x)})\\\\sin (-x) cos (-x) csc (-x)=cos(x)[/tex]

The answer is:

The simplified expression is:

[tex]Sin(-x)*Cos(-x)*Csc(-x)=Cos(x)[/tex]

To simplify the expression we need to use the following trigonometric identities:

[tex]Sin(-x)=-Sin(x)\\Cos(-x)=Cos(x)\\Csc(-x)=-Csc(x)\\Csc(x)=\frac{1}{Sin(x)}[/tex]

We are given the expression:

[tex]sin(-x)*cos(-x)*csc(-x)[/tex]

So, applying the identities and simplifying, we have:

[tex]Sin(-x)*Cos(-x)*Csc(-x)=-Sin(x)*Cos(x)*-\frac{1}{Sin(x)}[/tex]

[tex]Sin(-x)*Cos(-x)*Csc(-x)=Cos(x)*-Sin(x)*-\frac{1}{Sin(x)}[/tex]

[tex]Sin(-x)*Cos(-x)*Csc(-x)=Cos(x)[/tex]

Hence, the simplified expression is:

[tex]Sin(-x)*Cos(-x)*Csc(-x)=Cos(x)[/tex]

Answer:

Step-by-step explanation:

To calculate the number of yellow paperclips expected to be drawn if a paperclip is drawn 800 times, multiply the number of draws by the probability of drawing a yellow paperclip.

Therefore, if a paperclip is drawn a total of 800 times, a yellow paperclip is expected to be drawn roughly 180 times.

To calculate the number of blue paperclips expected to be drawn if a paperclip is drawn 80 times, multiply the number of draws by the probability of drawing a blue paperclip.

Thus, if a paperclip is drawn a total of 80 times, a blue paper clip is expected to be drawn roughly 21 times.

Finally, calculate the number of draws necessary if a green paperclip is drawn roughly 1,235 times, divide 1,235 by the probability of drawing a green paperclip.

Therefore, If a paperclip is drawn a total of 5,200 times, a green paper clip is expected to be drawn roughly 1,235 times.

The parallel lines are lines that are always at the same distance apart from each other and never touch. Also they must be drawn in the same plane.

Step-by-step explanation:

Consider the provided information.

The parallel lines are lines that are always at the same distance apart from each other and never touch. Also they must be drawn in the same plane.

The sketch that shows parallel lines is shown in figure.

The real life example of parallel lines.

Few examples are:

1) Railroad Tracks

2) Edges of walls

3) Zebra crossing

Parallel lines are straight lines that run in the same direction, never intersect, and maintain a constant separation distance, as seen in railroad tracks.

Parallel-Lines are two or more straight lines that run in the same direction and never intersect, no matter how far they extend. They maintain a constant separation distance between them, and their slopes (steepness) are equal.

In a sketch, parallel lines are depicted as lines that are equidistant from each other and do not cross, remaining at the same distance apart.

The sketch of parallel-lines is shown below;

A real-world example of parallel lines is railroad tracks. When you observe two railway tracks running alongside each other, they serve as a practical illustration of parallel lines. They remain equidistant throughout their length and never converge, ensuring safe and efficient train transportation.

Step-by-step explanation:

We know we have one single event with 3 outcomes. We can figure that 5 is the only other odd number not 1-3, so that means we have 3+1 outcomes

Ok, so no we know we have 1 singular event with 3+1 possible outcomes

This means the probability is 4/6, due to a normal die having 6 faces.

Therefore, the probability is 4/6, 2/3, or .666666......

The Probability of obtaining a number less than 3 or odd when a standard number cube is tossed is 2/3.

In probability theory, the question is asking for the possibility of tossing a number cube and landing on a number less than 3 or an odd number.

In a standard number cube which is a die, we have six numbers (1, 2, 3, 4, 5, 6).

Numbers less than 3 are 1 and 2.

The odd numbers are 1, 3 and 5.

However, 1 is common to both cases, so we add the total unique outcomes which are 1, 2, 3, and 5.

So, we have four favorable outcomes.

To find the probability, you calculate the ratio of the favorable outcomes to the total possible outcomes.

In this case, it will be 4 favorable numbers against 6 possible numbers altogether.

Hence, P(less than 3 or odd) is 4/6 which can be simplified to 2/3.
